Description
Aspartoacylase (EC 3.5.1.15, aminoacylase II, N-acetylaspartate amidohydrolase, acetyl-aspartic deaminase, acylase II, ASPA) is a hydrolase enzyme responsible for catalyzing the deacylation of N-acetyl-l-aspartate (N-acetylaspartate,NAA) into aspartate and acetate. It is a zinc-dependent hydrolase that promotes the deprotonation of water to use as a nucleophile in a mechanism analogous to many other zinc-dependent hydrolases. It is most commonly found in the brain, where it controls the levels of N-actetyl-l-aspartate
